Specification of Letters Patent.

Patented June 7; 191a.

Application filed January 29, 1910. Serial No. 540,803.

To. all "whom it concern: I

Be it known that I, WILTSHIRE S. GRAY, a citizen of the Hnittl States, residing at Indiana olis, in the county of Marion and State 0 Indiana, have invented a certain new and useful 'B0ttle-Dam, of which the following isa specification.

one-fourth of the total height of the bottle,

the lower level of the cream being thus at a point in the bottle having a diameter somewhere between the small diameter of the outlet and the larger diameter of the main body of the bottle. Under such conditions it. is quite diflicult to remove the cream from the milk without getting a considerable uantity of the skim milk which lies below t e cream.

The object of my invention is to produce a handy and efiicient little device by means of which the cream may be readily poured out from theHbottle while exit of any material quantity of the less -ri'ch milk below the cream is prevented.

The accompanying drawings illustrate my invention.

Figure 1 is a perspective view of my device showing the manner of insertion into a small mouthed bottle; Fig. 2 a similar view showing its position as a dam within of a slight/modification.

the bottle, and Fig. 3 a perspective detail .In the drawings, 10 indicates a circular sheet of transversely elastic material having, however, sufficient rigidity when supported at itsedge to serveas-a dam. This plate may be formed of any suitable mate rial, such for instance as very thin sheet steel, or celluloid, etc. In practice, howev'er,-I have found that a sheet of ver thin steehwill produce excellent results, an such materig'ilcan be readily kept entirely clean and does not impart any taste tothe milk or cream. Pivotally secured to one face of sheet -10 is a handle rod 11 provided at its lower end with an arm, stop or finger 12,

' qulred for which will limit the throw of the handle '11 in one direction.

The form of the pivotal connection between the late 10 and rod 11 is immaterial.

- In Fig. 1 it is produced by means of a saddle-piece 13 brazed or soldered to the face of the sheet 10; In the form shown in Fig. 3 a pair of parallel slits 14 are cut through the body of the sheet, and the body of the sheet. is struck up to form a saddle v15 beneath which a portion of rod llmay be 'ournaled. Rod 11 near its free end is nt into an eye 16 and the projectin tip 17 is sharpened so that this ,sharpene tip may be used for spearing into the usual fiber or paste-board stopper which is commonly used for closing thebottles, it bemg possible thereb to rea ily remove sucl1 'stop- -per from the ottle, the eye 16 forming a convenient finger hold.

In operation, the plate. 10 will be thrown up a ainst rod 11 and introduced into the mout of the bottle as clearly indicated in Fig. 1, a slight downward and transverse ressure pon the rod'll .into the mouth 0 th bottle serving to curl up the sheet 10 so that itmay be readily projected into the mouth of the bottle. The plate will be forced down through the cream until it is below that portion of the bottle which is of less diameter than the plate. Thereupon the plate Wlll swing down to a position substantially at right an les to rodll and a direct upward 'pull on t e rod will serve to bring the dam plate into the position shown in Fig. 2 where of the cream with its perimeter in contact cause the discharge of the cream or other .1t will lie approximately at the lower level liquid which lies above the dam while the V remainder of the liquid below the dam is retained. There may of course be some slight leakage past the dam but the time reouring off the cream is comparatively s ort and a slight leakage will not be at all material. y

' It will be readily understood that the package and that, while the particular form I fundamental feature of my invention resides of handle or other operating member shown in the'drawings is probably commercially the best yet, nevertheless, there may be many variations from the form shown without departing from the spirit of my invention.

I claim as my invention:

1. A bottle dam comprising a transversely elastic normally flat plate having a shape adapted to fit an internal diameter of a bottle exceeding the diameter of the bottle mouth, a handle rod pivotally connected to said plate upon an axis substantially parallel with the plate at one side of its center, and means for limiting the swing of said rod on the plate in one direction to a position substantially normal to the plate.

2. A bottle dam comprlsing a transversely elastic plate having a shape adapted to fit an internal diameter of a bottle exceeding the diameter-of the bottle mouth, a handle rod pivotally connected to said plate upon an axis substantially parallel with the plate at one side of its center, and means for limiting the swing of said rod on the plate in one 5 direction to a position substantially normal to the plate.

3. A bottle dam comprising a transversely elastic normally flat plate having a shape adapted to fit an internal diameter of a bottle exceeding the diameter of the bottle mouth, a handle rod pivotally connected to said plate upon" an "axis substantially parallel with the plate. and means for limiting the swing of said rod onthe plate in one direction to a position substantially normal to the plate'.

4. A bottle dam comprising a transversely elastic plate having a shape adapted to fit an internal diameter of a bottle exceeding the diameter of the'bottle mouth, a handle rod pivotally connected to said plate upon an axis substantially parallel with the plate, and means for limiting the swing of said rod on the plate in one direction to a position substantially normal to the plate.

.In witness whereof, I have hereunto set my hand and seal at Indianapolis, Indiana,

this twenty-fifth day of January, A. D. one thousand nine hundred and ten.
